J. K. ANDERSON VALVE CONSTRUCTION Filed -April 6,A 1929 gill/Illia lV (El) Patented May 20, 1930 JOHN IK. ANDERSON, OF MIDWEST, WYOMING VALVE CONSTRUCTION Application filed. April 6, 1929.

This invention relates to valve construction and more particularly to a construction of check valves'and the like.

An important obj ect of the invention is the provision of an arrangement such that the valve is constantly rotated during the passage of fluid thereahout and accordingly tends to engage its seat with a sweeping movement producing a grinding action.

A further obj ect of the invention is to produce a construction such that the seat is constantly kept clear of foreign matter during the passage of fluid through the valve.

A. still further obj ect of the invention is to l5 provide a device particularly adapted for use in the formation of standing and travelling valves of oil well pumping apparatus and which in addition to performing the function above set forth produces a whirling action of the fluids and gases passing upwardly therethrough, causing the same to thoroughly intermingle.

These and other objects I attain by the construction shown in the accompanying drawings wherein for the purpose of illustration I have shown a preferred embodiment of my invention and wherein Figure 1 is a vertical sectional View through a standing valve constructed in accordance with my invention;

Figure 2 is a plan view of the agitating element;

Figure 3 is a transverse sectional view through the agitating attachment;

o Figure 4 is a fragmentary vertical sectional view on lined- 4 of Figure 2.

Referring now more particularly to the drawing, the numeral generally designates an inlet tube, at the upper end of which is an enlargement as at 11l for the reception of a valve seat 12 upon which is seated a check valve 13. In accordance with my invention I fix within the inner tube 10 a worm` or spiral baffle 14, which may be conveniently L secured inthe present type of valve mount ing by providing the same with an annulus 15 rigidly secured thereto and adapted to seat upon the shoulder 16 formed by the enlargement 11, and being held in position f 'E thereagainst by valve seat 12.

Serial No. 353,144.

The upper end of this baffle is notched or otherwise formed as at 17, so that it will not interfere with seating of the valve, and it will, of course, be understood that if the check valve 13 instead of being of the ball type at present illustrated, is of the plumb bob type, the notching at 17 must be correspondingly deeper to accommodate the valve. Since the spiral baffle 14 is fixed, the fluid passing to the valve through inlet 10 is causedV to rotate and by its rotation will, when it is supportingthe.valve-18, cause a rotation of this valve. The whirling action thus produced will, of course, act upon the seat l2 to sweep sand or other foreign matter there-V from and keep this seat properly cleansed to insure the correct seating of the valve. Furthermore, the whirling action serves to thoroughly mix gases and oils passing upwardly through the valve.

While I have at present illustrated my invention as incorporated in the standing valve of oil well pumping apparatus, it will, of course, loe understood that the construction employed is not limited to use in this capacity. It may be employed anywhere where diliiculty is met in keeping a valve properly seated or in keeping the valve seat free from a collection of foreign matter.

It will, of course, be understood that the whirling limpulses given fluid passing through the valve by the worm 14, does not cease at the valve proper but continues abovev the valve with the result that sand and other foreign substances are held in suspension above the valve and carried out by the whirling fluid. This is particularly true in connection with the standing valve of oil well pumping apparatus where there Vis a working valve operating directly thereabove through which the whirling fluid will pass immediately after its passage through the standing valve.

Since the construction herein illustrated is capable of a very considerable range of change and modication without in any manner departing from-the spirit of the invention, I accordingly do not limit myself to such specic structure except as hereinafter claimed.

l. The combination With an inlet tube having a Valve seat and a valve coacting with the seat, of a spiral baie arranged Within and rigid to the tube beneath the valve seat for causing rotation of fluids passing through the tube to the Valve, the upper end of said bafie being notched in conformity to the contour of the valve to thereby permit approach of the baiile in close proximity to the valve adj acent the Wall of the valve seat.

2. In Combination with a tube, the bore of Which is enlarged at its upper end for reception of a Valve seat, a Valve seat engaged in the enlargement and a Valve coacting with the seat, of a spiral baffle arranged Within the tube beneath the valve seat and having secured thereto an annular member engaging in the enlargement beneath the seat and maintained by the seat against movement With relation to the tubeJ the upper end of said bafie being notched in conformity to the contour of the valve to thereby permit Close ap* proach of the baiie to the valve at the valve seat.

In testimony whereof I hereunto aiiiX my signature.

JOHN K. ANDERSON.
